1.10 DC Input Wiring
Input 1 can be used to monitor the stopping time of resolver 1 if the NX2A4E2 has channel 1 configured for a
single resolver transducer. This input is labeled “BRAKE” on the front of the unit. Input 2 is presently not
implemented on the NX2A4E2.
Input 1 is a differential input that can be wired to accept sourcing or sinking sensors. It accepts 10 to 30 Vdc
without the need for an external current limiting resistor. Figure T1.12 below shows how to wire discrete DC
sourcing and sinking sensors to input 1 of the NX2A4E2.

1.10.1 Cable Shields
Because they are low power signals, cabling from the sensor to the NX2A4E2 should be done using a twisted
pair cable with an overall shield. The shield should be grounded at the end when the signal is generated,
which is the sensor end. If this is not practical, the shield should be grounded to the same ground bus as the
NX2A4E2.
